THIS CRITTER IS KILLLING ME. It's a sea slug that has converged on a fish shape.
Here's a vid of it swimming https://vimeo.com/159589650
It's "pectoral fins" are Rhinophores, basically antenna for smelling. It hunts jellyfish, and uses the remnant of its Foot to stick to them.
@noiob it looks SO similar to the Ghost Leviathan i atted their twitter asking if its an inspiration
@Daylight I'm glad this one's a lot more cute and less scary
@Daylight Well Dolphins/Whales are mammals that have converged on fish shape too, Leviatan was a prehistorical sperm whale that was an apex predator that would also eat Meglodon so some were even shark like. Though most whales resembled prehistoric marine reptiles like Mosasaur more than fish for much of their history in the water.
@codeawayhaley Leviathan? like? from the bible?
@Daylight It was named after Leviathan from the bible, it was a sperm whale around when Meglodon was which likely fed on meglodon if meglodon didn't eat them first.
@Daylight Livyatan melvillei
@Daylight took me a while to figure out that that's a real animal, not something from Subnautica
